FIELD: petroleum industry.
SUBSTANCE: invention relates to preparing oil to further processing by dehydration and desalting oil with simultaneous protection of equipment against asphaltene-resin-paraffin sediments. The composition for destruction of water-oil emulsion comprises the following components, wt.-%: glycerol-base block-polymer of ethylene and propylene oxides with molecular mass 6000 Da, 30-45; oxyalkylated polyester resin diepoxide H-101, 2-20, and solvent, the balance. The composition provides the enhanced effectiveness in destruction of stable high-resinous water-oil emulsions in coal-carrying gallery with simultaneous protection of oil-field equipment against asphaltene-resin-paraffin sediments and enhanced degree of waste treatment in processes for preparing oil.
EFFECT: improved and enhanced effectiveness of composition.
